Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Previously, Red Hat Hyperconverged Infrastructure for Virtualization did not configure a system slice to limit the resource usage allowed to Red Hat Gluster Storage. This meant that when storage was under high load, it consumed too many system resources. Storage processes are now configured to use up to one third of system resources.	Story Points:	---

Description SATHEESARAN 2019-02-27 06:51:04 UTC

Description of problem:
-----------------------
As there are gluster and virt services are running on the same host/machines,
gluster slice setup is required to cap the number of cores consumed by gluster process. Gdeploy has gone with the standard value of 33% cores allocated to gluster process. The same needs to implemented with gluster-ansible roles too.

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
gluster-ansible-roles-1.0.4-3

How reproducible:
-----------------
Always

Steps to Reproduce:
-------------------
1. Complete RHHI-V deployment with RHVH 4.3

Actual results:
---------------
gluster slice is not configured

Expected results:
-----------------
gluster slice should be configured
